Adult worms lay eggs in the dog's small intestine. Eggs are passed then passed in the dog's feces. Eggs develop in the environment and become infective approximately 1 week after being passed in feces. Embryonated eggs can be ingested by transport hosts, such as field mice or earthworms, who become carriers of larvae.
How long does it take for worms to reproduce in dogs?

They can remain encysted in the dog's tissues for months or years.
